A DETECTOR FOR GRAVITATIONAL WAVES
The Detector 1 is continuously operating since 26 April 1994. The analysis the graphs performed with the data carried out these years have allowed discovering a series of completely new phenomena occurring in the Universe, among which, the existence of particular extra-massive Multiple Nucleus Quasars that seem to affect its operating.

Recordings & Graphs (Last updated: March 09, 2010)
Rome, 17 November 2009. On September 2009 the anode current of the Detector_3 was reduced. The detector will take some months to stabilize.
Rome, 13 May 2009. Due to troubles on the DAQ systems, readings for Detector_2 and Detector_3 from 1st to 14th April were lost and readings of Detector_1 from 21st to 29th of April were taken manually (one reading per day).
Rome, 12 November 2008. Graphs of other experimental CdS detectors were added. On June 2008, some readings were lost.
Rome, 18 September 2007. Readings for Detector_3b on July-August were taken manually due to troubles of the DAQ system.
Starting with 2007 a new series of nucleus collapses belonging to the same Multiple Nucleus Quasar (MNQ) has been detecting. The first one is quite well visible on March (a "fork" having the primary peak on 09 and the secondary peak on 22 of the month) whose distance between peaks is approx. 12 days. A second collapse having same characteristics was detected in the second half of May. In June-July two more partially overlapped "forks" of the same kind were also detected, whose distance between peaks is still 12 days. With a distance between peaks of 12 days, the width of wave is w=(12/11.5)*9.5=9.9 and redshift is z=w-1=8.9. The distance from us of the MNQ results as:Rome, 23 June 2007. Spikes on Detector_3b graphs on March through May are due to troubles of the multiplexer DAQ system.
Rome, 07 September 2006. A new MNQ nucleus collapse has been detected (more clearly by the Detector_1 and less clearly by Detector_3b, ) between the end of July and the beginning of August. The distance between peaks is approx. 5.5 days (z approx. 3.5). Therefore, also this nucleus belong to the same MNQ whose general collapse started in the last winter.

Rome, 11 June 2006. The recording of the MNQ general collapse has been continuing, with the collapse of a new nucleus recorded at the end of May 2006.
Unfortunately, due to a failure of the hard disk of Detector_3 computer we lost some (7 days) data on May.
Rome, 14 May 2006. In the first half of April 2006 a new nucleus collapses has been detected, that seems to belong to the same MNQ.
Rome, 12 April 2006.
On the beginning of 2006 two new nucleus collapses has been detected.
Both collapses have the distance between peaks of approx. 5.5 days. Therefore, the width of wave is w=(5.5/11.5)*9.5=4.5 and redshift is z=w-1=3.5.
This collapsed nuclei belong to the same MNQ whose distance from us results as:
r0=RU*z/(z+1)=RU*3.5/4.5, that is approx. 78 percent of visible Universe radius RU.
Unfortunately, in the first months of the year the sensitivity of detectors becomes lower because of the signal is over helmed by an year-period standing gravitational wave, which has its minimum on 10-12 of March and its maximum on September as it is shown in the whole graph. The amplitude of this wave is approx. 0.5 Volts.
This is due to a "flow" of space that continuously invest the Earth during its orbital motion about the Sun. On September the Earth is going in the same direction of space while in in March in the opposite one.
In the meanwhile, the interaction between this "gravitational wind" and the Earth magnetic field becomes the highest in June where the (relative) velocity variations have a maximum. A remarkable effect of this interaction is the rapid slowing down Earth undergo during this month (approx. 2 milliseconds of reduction of the Length-of-Day), as shown in the graph.
A quite similar effect seems to occur to the Sun in its 11-years period.
Rome, 21 January 2006. In December graphs we have also included the recording of Detector 3b but this detector is still recovering after modifying the operating parameters carried out on last November (a few milli Volts fluctuations on the anodic voltage, due to the temperature, was eliminated and the anodic current was increased from 3.87 mA to 4.23 mA in order to improve its sensitivity).
Rome, 10 December 2005. In the last November, we modify some of the operating parameters of Detector 3. We restart publishing the graphs on January 2006.
Rome, 7 September 2005. After the failures occurred in July, Detector 3 is still recovering.
Rome, 10 August 2005.
The collapse started on the end of June has a distance between peaks of approx. 10 days. Therefore, the width of wave is w=(10/11.5)*9.5=8.3 and redshift z=w-1=7.3. So that, the distance of collapse results:
r0=RU*z/(z+1)=RU*7.3/8.3 approx. 88 % of visible Universe radius RU.
Unfortunately, on 28 June the Detector 3 temperature-controlled external enclosure failed. The event disturbed a little the detector's operation (anode voltage variations of some mVolts). During the external enclosure setting up, there were two more variations occurred on 19 and 22 July. On 28 July it was definitely fixed.
Rome, 10 September 2004: On 23 August the data acquisition system of Detector N. 1 failed and was out of service until 1 September. Also the one-day manual readings were not available and the graph was completed with the help of
Detector N. 3 data.
A quite big "fork" with 8.5 days of distance between the peaks has been detected.
The redshift of this collapse is z= 6.0 and the distance from us, at the time of collapsing, was 86 % of the visible Universe radius.
After more than one year of a "gravitational stillness", the effects produced by this wave can be noticeable quite well.
The impact of this gravitational wave with the Earth magnetic nucleus has caused many deep earthquakes, particularly during the rise front of the wave and during the peaks where the changes of the slope of signal are higher.
Furthermore, many volcanoes around the world have been re-activating. In the next weeks it will be more evident.
Because of the higher magnetic field, the interaction of this wave with the Sun was stronger. In the next months (the Sun needs more time to show it) its effects will reach the surface and an increase of the number of sunspots,
flares, flux of energetic particles, etc... can be observed as well.
Rome, 19 April 2004: Data of beginning of February have been restored, while some data of March were lost.
Rome, 9 March 2004: Some troubles with the Personal Computer caused the lost of some Detector N. 3 data of beginning of February. We are trying to recover them.
Please, note that the quite small ripple on Detector N. 3 data on 2 January 2004 is due to the Wheatstone bridge zero-adjusting.
Construction of the Detector (P. Galletti and A. Aluigi)
Rome, 28 February 2005
The report describes the construction of the detector for Gravitational Waves that uses CdS photoresistors. It gives informations for its construction as well as electrical diagrams for power supply, anode current regulator and temperature regulators.
Moreover, there are informations for set up and tuning the detector, which include also the initial period we called "formatting" where, with passing the time, the detector becomes more and more sensitive to Gravitational Waves.

Part 7: Redshift (P. Galletti and A. Aluigi)
Rome, 31 March 2004
The preliminary redshift analysis of highly intensive gravitational waves performed
at the end of 2000 (see Appendix of Part 2) has been updated. The reasons are the following:
- more gravitational waves have, in the meantime, reached the detector (particularly in 2001 and 2002);
- the evaluation of wave intensity has been improved by the using the amplitude of its "rebounding" too;
- the intensity of the first waves detected in 1994 should be cautiously considered because of the "formatting" period was not completed yet.

Part 6: The collapsing of Multiple Nucleus Quasars (P. Galletti and A. Aluigi)
Rome, 20 January 2003
After the two collapses of high intensity happened in August 1999 and for about one year, a reduced number of gravitational waves investing the Earth and our Solar System.
Beginning from July 2001 a rather relevant "gravitational activity" has restarted. The analysis a single event concerning the general collapsing of a MNQ that happened at very long distance from us helped us to better understand these extraordinary phenomena continuously happening all over the Universe.

Part 5: More on the "Birth" and "Death" of Matter (P. Galletti and A. Aluigi)
Rome, 28 February 2002
The ``death'' of old matter as well as the "birth" of new matter into the Universe are further investigated.
The set up a new Data Logger (Agilent 34970A) has allowed to start a new series of data acquisitions with an increased frequency of readings. This increase of time resolution, has allowed to find out the exact shape of the "notches" and further reduce the uncertainty about the size of the nuclei of the MNQs at the moment of their "exit" from the Universe.

Part 4: The detector "puzzle" (P. Galletti and A. Aluigi)
Rome, 31 August 2001
After more than two years tests about the operating of the detector and checking the graphs produced by same, our conclusions about the detector behaviour indicate that it is impossible to find any justification in the present Laws of Physics. In other words, it is impossible to give a simple and satisfactory explanation of its behaviour, without rejecting some of the principles that form the basis of today's Physics.

Part 3: "Birth" and "Death" of Matter (P. Galletti and A. Aluigi)
Rome, 31 August 2001
The assembling of a LED sensor has allowed a further improvement of the time resolution,
allowing to record also events having a very small intensity and revealed by the presence of "notches"
overlapped on the main signal recorded by the detector.
These lower intensity phenomena, as well as the discovery of MNQs, has led us to deeply revise the mechanisms showing how the Universe works and where the old matter "death" by the peculiar mechanism of cosmic collapses and new matter ``birth'' into the Universe.
A first attempt to lay down a preliminary balance of matter for the Universe is described, also if some points are still uncertain.

Part 2: Multiple Nucleus Quasars (P. Galletti and A. Aluigi)
Rome, 15 February 2001
The analysis of the graphs carried out by the detector since 1994 up to now has allowed to discover a series of completely
new phenomena occurring in the Universe, among which, the existence of particular extra massive Multiple Nucleus Quasars (MNQs), that seem to affect its operating.
The analysis of a specific event recorded in summer 1995 allowed us to find the solution of the "redshift" problem related to these waves and, therefore, the distance from us of the events that have generated them.
The problem concerning the detector calibration, that is about the physical meaning of the voltage signal recorded by the detector, is also investigated.

Part 1: Description and operating of the detector (P. Galletti and A. Aluigi)
Rome, 30 September 2000
The report describes a detector for Gravitational Waves conceived and built in 1994.
The behaviour of this simple instrument, which consists of Wheatstone bridge where in one of the two arms is located a cadmium-sulphide photo-resistor (CdS) illuminated with a constant source of light emitted by a vacuum diode, was considered, since the beginning, "anomalous".
The instrument is continuously operating since 26 April 1994 and graphs produced with the data recorded until 30 June 2000 are presented.
